Curriculum Vitae

Sergio Brovelli was born in Italy in 1978. Currently, he is Associate Professorship in Experimental Physics at the Department of Materials Science of the University of Milano Bicocca in Italy. He graduated in 2003 and earned his PhD in Materials Science (2006) at the University of Milano Bicocca thanks to a fellowship by the Tronchetti Provera Foundation. Awarded with a fellowship by the Della Riccia Foundation (2006) he moved to University College London and London Centre for Nanotechnology (UK) where he received a Marie Curie Research Fellowship that funded his research until December 2009. In 2010, he moved to the Los Alamos National Laboratory where in 2011 he was awarded with the Los Alamos Director’s Fellowship. In 2012 he moved back to Europe as Assistant Professor at the University of Milano Bicocca and in 2015 he was tenured with the Associate Professorship in Experimental Physics. His research revolves around physical processes confined at the nanoscale in relation to the composition and nanoarchitecture of organic and inorganic nanostructured materials and their impact on photonic devices (photovoltaic, lighting, sensors, biomedical).

In 2016, together with Academic and Industrial partners, he founded the spin-off company Glass to Power srl (www.glasstopower.com) aimed at the industrialization and commercialization of Photovoltaic Windows based on Luminescent Solar Concentrators developed and patented by his team.

In May 2014 he has been Program Committee Chair of the 8th International Conference on Quantum Dots (QD2014) that was held in Pisa, Italy. In May 2012 he has been Local Organizer of the 7th Edition of the same Conference Series that was held in Santa Fe, NM, USA.

In 2014 he was finalist of the Young Researcher Award of the International Union of the Materials Research Societies.

Between 2007 and 2010 he has been Scientific Project Manager of the European Research Training Network “Threadmill” (MRTN-CT-2006-306040), where he was responsible for the direct interaction with the European Commission for the coordination of eleven partners in eight European countries.

He received specific training in project management, intellectual rights protection, European funding schemes and strategies in innovative industries (London Business School, 2008).

Currently, he is referee for numerous high impact scientific journals including Nature, Nature Photonics, Nature Nanotechnology, Nature Communications, Nano Letters, ACS Photonics, Advanced Materials, Advanced Functional Material, Advanced Optical Materials, and other Wiley, ACS, Elsevier, IOP and AIP journals.
